I'm sure he will invent some unfathomably dumb way to fuck it up regardless of any failsafes.
Problem with vtuber corpos is, almost all of their value is tied to IP. And vtuber IP is the only thing that's absolutely impossible to liquidate. You take loan, buy models and assets, advertisement, finance MVs and concerts etc etc, but you can't resell any of it. Most you can do is to transfer employment contract together with everything else, but how you gonna value all of it? Especially with niji rabid audience who are fans of a corpo instead of creators. And as a cherry on top, talent can legally dip out of this at any moment.
